One name - one fungus: the influence of photosynthetic partners on the taxonomy and systematics of lichenized fungi
No full textLichens are fungi (mycobionts) that form symbiotic associations with
photoautotrophic prokaryotes or eukaryotes (photobionts); however, some
species can exchange photosynthetic partners during their lifecycles. This
phenomenon modifies the morphology of lichens and consequently influences
the taxonomy of lichenized fungi. Here, a few such cases in which the photobionts
influenced the taxonomy and systematics of lichenized fungi are reviewed. Two
different morphotypes of the same species – known as photomorphs – were
classified as different species and sometimes different genera. Moreover, different
types of photobionts and the absence or presence (optional lichenization) of an
alga in the thallus were believed to be diagnostic characters for discriminating
genera. However, the taxonomy and systematics of lichens are based always,
according to Article F.1.1. of the International Code of Nomenclature for Algae,
Fungi, and Plants, on the fungal partner and only one name is applied
